2. AUDITORY SYSTEM RESPONSIBILITIES Central auditory processes are responsible for… Sound localization, lateralization Auditory discrimination Temporal aspects Competing signals Degraded signals APD: Inability to do one or more of the listed behavioral processes

3. TYPES & ISSUES 4 main types Phonetic decoding Tolerance-fading memory Auditory integration Prosodic Difficulty with… Extra noise Long conversations Phone Foreign language Challenging vocabulary Remembering spoken information Taking notes Multi-step directions

5. INCIDENCE AND PREVALENCE Auditory Processing Disorder effects 3-5 % of children (Chermak and Musiek 1998) 2 to 1 ratio between boys and girls The 10 – 20 % of adults with APD are likely affected due to Neurological disorders, diseases, and insults, including neurodegenerative diseases Less than 5 % of the incidence of APD in children is thought to be caused by such diseases

6. DIAGNOSIS AND ASSESSMENT Multidisciplinary team of psychologists physicians teachers parents audiologists speech-language pathologists Audiologists diagnose – test for hearing and processing problems – test central auditory system, peripheral hearing test to determine hearing loss and perform electrophysiological and behavioral tests Other team members observe and assess using checklists of auditory behaviors APD is often misdiagnosed since characteristics of APD can also be found in learning disabilities, ADHD and depression. (Kids Health)

7. TESTING Audiologists look for problems with one or more of the following auditory tasks: Sound localization and lateralization Auditory discrimination Auditory pattern recognition Temporal aspects of audition (resolution, masking, integration, ordering) Auditory performance decrements with competing acoustic signals Auditory performance with degraded acoustic signals

8. FAMILY ISSUES Misdiagnosis Be sure your child is “ready” to listen Judgment from other parents/teachers Social situations Common APD features Needs comments repeated “Ignores” people Asks extra questions Literal Lack of self confidence

9. INTERVENTION STRATEGIES Classroom Management of a Child with Auditory Processing Problems Environmental Modifications Classroom Placement Classroom Seating Quiet Study Areas VisuaI Aids Compensatory Strategies Look and Listen - Gain Attention Check Comprehension Rephrase and Restate Pre-Tutor Monitor Efforts - Inform Parents APD Classroom Modifications Checklist Assistive Technology Section §300.5 Assistive technology device …, assistive technology device means any item, piece of equipment, or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve the functional capabilities of a child with a disability. (Authority: 20 U.S.C. 1401(1))

10. CURRENT RESEARCH ASHA What causes APD? Genetics? Neurologic abnormality Developmental delay Combination of factors Drugs? Relationships among auditory processing, attention, cognition, and language. Cynthia Riccio & George Hynd Correlation between ADHD and APD Intervention Study – Various intensive interventions show positive results (Gillam, 2008)
